A woman traveling with her teenage children was arrested after U.S. Customs and Border Protection officers found 125 pounds of marijuana in the van she was driving Saturday at the Santa Teresa border crossing, CBP officials said Monday.

Faustina Laura Barriga Hernandez, 40, of Chihuahua City, Mexico, was turned over to U.S. Immigration and Customs Enforcement agents to face smuggling-related charges, officials said. The woman's 19-year-old son, 13-year-old daughter and a third person in the van were released.

Officials said that the marijuana packages were found hidden in the side panels of the van during an X-ray scan.
